Why silicone and plastic vulcanization in the mold will appear part of the sticky, part not sticky?
29 Oct 2019
According to the experiments of various kinds of silicone adhesive plastics, the scheme given by the department of conlibon silicone glue is as follows:
1. The surface of the plastic is not cleaned, that is, some parts of the plastic are clean, some parts are greasy, dust, etc., resulting in non-stick silicone and plastic (just go to the machine after cleaning).
2, the plastic surface coated with silicone glue (silicone treatment agent) is not uniform, resulting in silicone and plastic non-stick;
(conlibon silicone glue can be used for spraying, brushing, soaking and other operations to treat the plastic surface)
3, plastic coating brush surface treatment agent, in a timely manner, operator hands have oil or a lot of water, grasp the plastic parts, resulting in the plastic parts and silicone not stick
4, plastic parts have a combination of different parts, there is crack in the middle, the silicone material is placed in the computer, didn't pay attention to the places in the gap left interval, cause at the time of closing the gap of the air inside of plastic parts can't discharge, cause the crack location on bubble plastic and silicone non-stick (put silica gel material, cut the silicone in gap position);
5, the plastic material is not uniform, resulting in the silicone glue can not activate its molecules, resulting in the plastic and silicone not stick.
